- Chemistry Department, Guru Nanak Dev University, Amritsar-148 005 Manuscript received 20 September 1980, revised 17 March 1982, accepted 28 September 1982 Complexes of Sm(III). Gd(III), Dy(III), Er(III) and Yb(III) with glycyl-L-proline have been investigated by the potentiometric titration technique in aqueous medium at μ + 0.15 M (KNO3), The proton-ligand stability constants and formation constants of the complexes have been determined by the Calvin-Bjerrum \(p\)H titration technique. The log K values have been determined by different methods. 1 he overall changes in ∆G, ∆H and ∆S have also been evaluated.
